Wolsong 3 Full Scope Simulator Conversion
• Repurpose Wolsong Unit 1 (W1) Full Scope Simulator (FSS) to become primary training simulator for Wolsong Unit 3 (W3)
• Two plant simulation baseline sources– Wolsong 1 FSS – nearly completed– Wolsong 2 FSS – modernization RFT 4Q 2008
• Extensive changes to the W1 FSS panels to make them specific to W3– W1 MCR Panels returned from South Korea to Canada for
rework– Largest part of work
12

Wolsong 3 FSS Conversion – Scope Overview
• W1 FSS MCR panels reworked to accurately represent W3 MCR • W1 FSS Computer and Peripherals repurposed• Plant Models
– Adjustments to W1, W2 simulation models already developed and validated – Addition of two simulated systems
• Severe Accident Simulation (SAS)– W1 FSS SAS to be carried over and updated to be W3-specific– 2D and 3D SAS graphics updated
• W1 FSS Virtual (Soft) Panels modified to be W3-specific• Active Schematics
– Majority of W1 FSS active schematics reused with minor modifications – Electrical distribution schematics redeveloped
• Digital Control Computers* (DCC) emulation for W3• W2 FSS Mark V and AVR systems reworked to accurately represent W3
*DCC systems used to monitor and control all major reactor and power plant functions

Main Control Room Panels
• Rebuild of W1 FSS MCR Panels to make W3-specific FSS (19 20 sections)– W1 cabinet housing retained – Panel modules 1000, 2000 & 3000 changed
for W3 FSS– W1 FSS instruments and components
reused wherever possible– W1 FSS components that cannot be reused
catalogued and returned to KHNP with delivery of W3 FSS
• New Fire Protection Panel • I/O system components (Beckhoff
compact I/O and Power Supplies) repurposed from W1 FSS
• All cabling and wiring redone

Main Control Room Panels
• Main differences between W1 FSS and W3– Panel Modules 1000/2000/3000 could not be
salvaged– DCC (RAMTEK) Monitors could not be
salvaged– Annunciators could not be salvaged– Micromod Controllers completely different for
W3– Switches Approx. 20% salvaged; most
switches have different positions– Meters Approx. 70% salvaged with 90% of the
scales changed– Pushbuttons Approx. 200 additional
pushbuttons added for W3– Panel Color & Texture Very similar to W1 – Miscellaneous Blanking plates, wiring labels,
escutcheon plates, gravoply/lamacoids, etc. to be redone

Computers and Peripherals, Software Platform
• W3 FSS C&P layout similar to W1 FSS– W1 FSS computer hardware and
network equipment repurposed for W3 FSS
– New PCs used for Mark-V HMI
• Commercial off-the-shelf software from W1 FSS reused for W3 FSS– Reinstallation from scratch
• Latest L3Harris Orchid® toolset for W3 FSS Conversion project

Plant Models
• Reactor and RCS models from W1 FSS– Already developed and thoroughly validated during W1
FSS FAT– Calandria (Reactor Core)– Steam Generators– Reactor Coolant System (Shutdown Cooling, Primary
Heat Transport (PHT), Pressurizer)– Reactor Auxiliary Systems (Containment Isolation,
Channel Temperature Monitoring)– Adapt for W3
– Redo connections between the process systems and I&C
– Recalibrate the PHT and reactor per W3 reference plant
• Remaining process models taken from W2 FSS– W3 much closer in design to W2 than to W1– Adapt models to match per W3 reference plant
• New Simulated Models (not part of W1 FSS)– Hydrogen Monitoring System– D2O Supply System
18

Severe Accident Simulation
• MAAP4-CANDU model from W1 adapt for W3– Previously integrated and validated with Core and RCS– MAAP4-CANDU adapted to include W3 MAAP4 parameter
file– Visualization graphics enhanced
• Systems replaced by MAAP4-CANDU during SAS – Containment & Reactor Vault– Calandria– PHT System– Steam Generators
• MAAP4-CANDU interfaces to Orchid® models– Emergency core cooling system (ECCS) – Shutdown cooling, feed and bleed– Moderator and end shield cooling – Dousing system, – Containment HVAC, – Feedwater, blowdown and main steam and I&C

Conclusions
• KHNP and L3Harris changed a bad situation into a win-win project• Leveraged work done on W1 FSS and W2 FSS, enabling quick
development of W3 FSS• Most of project team from W1 FSS redeployed for W3 FSS Conversion
ensuring continuity• L3Harris developed both the W1 FSS and the W3 FSS Conversion on
time and on budget• Our start in power plant simulation was on CANDU simulators (1973)
always fun to deploy another
